Borderline Personality Disorder - Diagnosis

Diagnosis

Diagnosis is based on a clinical assessment by a qualified mental health professional. The assessment incorporates the patient's self-reported experiences as well as the clinician's observations. The resulting profile may be supported or corroborated by long-term patterns of behavior as reported by family members, friends, or co-workers. The list of criteria that must be met for diagnosis is outlined in the DSM-IV-TR.

Borderline personality disorder was once classified as a subset of schizophrenia (describing patients with borderline schizophrenic tendencies). Today BPD is used more generally to describe individuals who display emotional dysregulation and instability, with paranoid ideation or delusions being only one criterion (criterion #9) of a total of 9 criteria, of which 5 or more must be present for diagnosis.
